Dakota Fanning on her first nude scene

Actress is all grown up... and nekkid

Trauma, here we come. The youthful Dakota Fanning is showing everybody just how grown up she is — by taking it all off for a sex scene in an upcoming film.

This might make you a little queasy… You've been warned.

Remember how cute Dakota Fanning was in I Am Sam? Well, that image is about to be effectively ruined. The 18-year-old actress has wrapped up her first nude sex scene in her newest film endeavour, Very Good Girls, co-starring Elizabeth Olsen and Boyd Holbrook.

Sweet mother of all that is good and pure in this world… This just makes no sense to us. First of all, Dakota is 18 years old? Reeeally? Second of all, she's doing naked things while also being naked? This physically hurts us.

The film recounts the story of two best friends (Fanning and Olsen, of course) who are desperately trying to lose their virginity and end up falling for the same guy. Draaaama! In case it wasn't clear, sex is involved…

"Yeah, well, I've never done that before, and I'm very newly allowed to do that," she explained to MTV News. "I was newly 18, so yeah, it was... It's kind of a sensitive thing, but it's a part of life."

Say it ain't so! We're not ready for this…

If you're interested to see Fanning naked (you pervert, you!), then wait for the film to emerge in theatres. Opinions?
